To all whom it may concern:

Be it known that I, 'JACOB Fnnpnmcx HUBER, a citizen of the United States, residing in Philadelphia, Pennsylvania,-have invented certain Improvements in Liquid- .Dispensing Apparatus, of which the following is a specification.

My invention consists of an improved liquid dispensing. apparatus and is particularly adapted for use on bars, soda water fountains orth'e like where liquids under high pressure, such assoda water and seltzer are dispensed.

My invention is of that class where a plurality of liquids are simultaneously dispensed through a common nozzle or outlet in such a manner that they will be mixed; this latter feature being particularly serviceable for dispensing flavored soda water, seltzer or the like.

One object of my invention is to construct a dispensing apparatus which will simultaneously deliver liquid under high pressure and other liquid, said apparatus being so arrangedv as to" prevent leaking of the liquids therethrough when the same is not be- 7 in operated. I

Another object is to provide a dispensing apparatus which will be of extremely simple construction, easy of operation and will take up very little space.

These object and other advantages'I attainin the following manner, reference being had to the accompanying drawings in Figure 1, is asectional elevation, of a dispensing apparatus constructed in accordance with my invention and showing certain of the elements thereof partly in outside view; Fig. 2, is a sectional elevation of the lower portion of my invention showing certain of the parts in different positions from those occupied in Fig.1; Fig. 3, is a sectional plan v1ew taken on the line H Fig. 1 Fig. ,4, is a sectional plan view taken on the line bb .Fig. 2; Fig. 5, is a sectional plan view taken on the line 0 -0 Fig. 1; Fig.

' 11; Fig. 13, is a'perspective view of a spht spring ring which I employ; and Fig. 14,

= is a perspective view of a turning cap and portion of aspindle which form part of my invention.

Referring to the drawings, 1 is a base section or casing which is provided with screw threads 2 for the reception of a liquid container or tank 3; the latter having a removable flanged cap 4 through passes a spindle 5,. This-spindle which is vprovided'with a handle 6 at the upper'endand a valveturning cap 7 at its lower end.

The base section 1 is provided with a tapered or frusto-conical bore 8 which extends through. the base section and forms the seat for a frusto-conical plug valve 9.; the latter having a head or nut 10 which isadapted to be engaged and turned by the cap 7 when the handle 6 is actuated to turn the spindle 5. A. port or passage 11 leads from the bore 8 into a chamber passage 12 and a threaded inlet sleeve 13 is screwed within the base 1 and is provided with an inlet passage 14 which leads to the chamber 12. .An annular flange 15 projects from the base 1 and forms a continuation of the port or passage 11 and a seat for a'cut-ofl valve 16 aswill be more fully described hereinafter.

An inlet tube ,17, which conveys a liquid under high pressure such for example as soda water (carbonated water) ,"-seltzer, or,

the like, is provided with a screw threaded portion 18 which tightly fits within the outerend of the passage 14.

The cut-off valve-16 is preferably constructed as-follows: A sleeve 17 havingl a flanged annular head,18- is provided wit a plurality of grooves 19 which extend longitudinally into its.outer surface and terminate in a slotted end 20. These grooves 19 form the passage for the high pressure liquid when the valve 16 is open as shown in Figs. 2 and-4. A washer or gasket 21 abuts the outer end of the flanged annular head 18 and is held thereto by a screw threaded collar 22 which has an inner annular flange 23 resting against the said washer 21. A Storm 24 passes through the washer and. the sleeve 17 and has an enlarged portion 25 which forms a shoulder 26 forqabutting the of the stem 24 pro washer 21. ln-assembl-ing the parts of the valve 16 the stem 24 is passed through the washer 21 and into the sleeve 17 so that p the shoulder 26 will abut and'compre'ssthe" washer 21. The stem is held inothis posi-- tion by a-clamp or other means and the stem 24. is soldered to the sleeve 17" at the opposite end 27. The collar 22 is then screwed on to the head 18 of the sleeve 17 until the fiange 23 abuts the washer and the edge 28 of the collar 22 is then beaded'or bent toward the bodv of the portion of the sleeve 17 so that in this condition the washer 21 is wedged or securely held in the position clearly shown in Fig. 11. 4

When in, position and when the-apparatus is not being operated the .washer21 abuts the annular flange 15 and the outer end 25 'ects within the frustoconical bore 8 as 0 early shown in Figs. 2 and 3. The pressure of. the liquid which enters through the port 14 through the ,pipe 17, acts against the valve 16 to securely close the port '11 from the chamber 12. However, '1 provide a coiled expansion spring 30' and so place the same that it encircles the sleeve and abuts the head 18 of the valve16 and the shoulder 31 formed in the inlet sleeve 13, so that even though-the pressure of the incoming liquid through the pipe 17 I is reduced or entirely cut-ofi the spring 31 will hold the. valve against the flange 15 and thereby close the port 11.

' A liquid inlet passage 32 extends into the base 1 and is in communication with the interiorof the liquid container or tank 3 and a second inlet passage or port 33; the latter alsoconnecting with the bore 8.

r For purposes of regulating the amount" of liquid which passes throughthe port 33 I provide a screw threaded shank 34 having a thumb nut 35 in the present instance, and whose inner end 36 is arranged to extend into'the liquid inlet 32.

The valve 9 in the present instance is providedwith a series ofducts 37, 38 and 39 which communicate with a main transverse or segmental duct 40; the latterhaving an enlarged portion 41 which is positioned,- when the stop valve 16 is seatedagainst the flange 15, so as to allow the end 25 of the stem or rod 24 to project therein as is clearly .-"sh own in Figs. 1 and 3. A cam face 42 is 'ofi valve'16 and force the latter-away from '60 f ormed within the valve 9 andmerges or '55 blends into the surface forming the said enlarged portion 41 as clearl shown in Figs..3, 4 and 10. This cam ace 42 is so placed as to engage the end 25 of the cut-' the flange 15 as shown in Figs. 2 and 4. The du'cts or grooves 37 38 and 39 extend downwardlyin the valve 9 and connect with an annular groove 43; said groove being substantially semi-circular in cross section in the present instance.- I also provide a sec-' ondgroove theconstruction illustrated and'the purpose of these grooves will be more fully described hereinafter.

A discharge aperture or passage 45 extends within the valve 9 andregisters with the bore 46in a sleeve 47 the latter being screwe'd within a counterbored portion of the valve 9 and being provided with an annular flange48- A- transverse passage 49 is formed in the valve 9 and extends from the outer surface thereof to the discharge passage 45 being so positioned that it will at times register with the shown in Fig. 2. The valve 9 is kept in its proper position within the casing by means of a spring 50 which encircles the lower portion of the said valve 9 and abuts the flange 48 of the sleeve 47 and the lower portion of the base 1. Also, thelower portionof the base 1 is screw-threaded at-51 and a nozzle or liquidinlet port 33 as deflecting collar 52 is-screwed thereon. The

end of the base 1 is provided with a series of angular or inclined nicks or notches 53 Which-are so arranged as to form communication between thegrooves 43 and 44in the said valve 9'and allow fluid to pass from the said" grooves the;- interior of the nozzle. or

collar 52. The lower 'portion of the inner surface of the collar 52 is inclined as shown at 54in the present instance and this arrangement causes a deflection of the downcoming high pressure fluid which, when the stop valve 16 is open, flows through the main duct 40 anddown through the ducts 37,38 and 39. t t

The transverse passage 49 is so arranged with respect to the enlarged portion 41 of the duct 40 that when the end 25 of the valve 16 is extending into the latter and the valve 16 is closed the said transverse passage will beout of register with the port 33 so that no liquid will be able to pass through the liquid inlet into the discharge passages 45 and 46. When the several parts are in the positions shown in Fig. 1 the stop valve 16 prevents the passage of the high pressure liquid and the port .33 is stopped by a solid portionof the valve 9.

The upper portion of the base 1 is cut away at 55 and a limit pin 56 in the valve 9 pro ects wlthin therecess thus formed and thereby limits the rotary movement of the said valveto the distance beween the surfaces 57 and 58. This distance, however, is sufiicient to permit the valve 9 being moved to bring the passage 49into register with the port 33' and the cam 42 into contact with the end 25 of the valve 16 with consequent opening of the port 11 to the chamber 12.

In the present instance the turning cap 7 isprov ded with apertures 59 and 60 which are adapted to allow the ears 61 and 61 of the nut 62 on the valve 9, to pass therethrough so that when the spindle 5 is turned ioo by the handle said valve 9 will also be turned. This latter construction permits the spindle 5, handle 6, and cap 4 to beeaslly and quickly removed from the tank 3 so that the tank may be easily filled.

As a matter of convenience it is considered that the tank 3 contains a flavoring extract and the tube or pipe 17 is connected With a source of high-pressure liquid such as seltzer. When the several parts are in the positions shown in Figs. 1 and 3, no

liquids will be dispensed through the'aper tures. However, when the valve 9 is turned into the position shown in Figs. 2 and 4 where the cam 42 acts to open the valve 16 against the pressure of the seltzer and the passage 49 comes in register with the port 33, the flavoring liquid will flow from the tank through the passage 32, 33, 49, 45 and 46, and outward into any receptacle. At the same time the seltzer will pass through the grooves 19 in the sleeve 17 through the chamber 12, port 11 and ducts 40, 37, 38 and 39, groove 43, and notches 53, into the, interior of the mixing or deflecting nozzle 52 where it will be deflected by the surface 54 toward the path of the down-coming flavoring liquid and will mix therewith. I find that the lower portion of the curved surface of the groove 43- and the inclined notches or nicks 53 allow the equal distribution of the seltzer or other high pressure liquids around the end of the base 1 and result in a proper mixing of the liquids dispensed. The surface 54 may be at any angle desired to cause more or less complete mixing of the liquids and any portion of the liquid which does not pass through the notches 53 will run into the groove 44 from whence it can escape through the spring50.

If it is desired to dispense a smaller amount of flavoring with the seltzer, the thumb nut 35 is turned so that the end 36 extends a greater distance into the passage 32. On the contrary, if it is desired to dispense a greater amount of flavoring with .the seltzer the thumb nut 35 is turned in an ing the ports but also has means for dispensing the liquid in the manner described. Also, the construction of my invention is such that the passage of the high-pressure liquid therethrough will not tend to force any of the flavoring extract backward into the tank 3 as the liquids are'not mixed until valve 16 is closed its end 25 extends within the recess 41 of the valve 9 .but does not touch the latter. By this construction the pressure of the high-pressure liquid does not aflect the valve 9 when the cut-ofl valve is closed.

The tank 3 may be of any size,.or two or more tanks can be connected with the passage 32 if it is so desired.

By having the form of cut-off valve shown at 16, if the washer 21 becomes worn the parts may be taken apart by heating the soldered end, substituting a "new washer, and re-soldering the 'said end.
